Bio 103 Chapters 1-5 questions
with verified answers
Describe how living things show hierarchical organization - correct answer it progresses from atoms to
the biosphere. At each higher level, emergent properties arise that are greater than the sum of the
parts.
Describe the nature of science - correct answer observation & reasoning
What methods are used to understand & study science - correct answer science is concerned with
developing and increasing accurate description of nature through observation experimentation
What are two types of reasoning used in science to draw conclusions - correct answer 1) deductive
2) inductive
What does deductive mean - correct answer applies general principles to predict specific results
What does inductive mean - correct answer uses specific observations to make a general rule
What are the steps in order used in the scientific method - correct answer
What does variables mean - correct answer processes that are influenced by many factors
What does control experiment mean - correct answer that variable is left unaltered
What does test experiment mean - correct answer one variable is altered in a known way to test a
particular hypothesis
,Give an example of how predictions are used - correct answer provide a way to test the validity of the
hypothesis
What does reductionism mean - correct answer attempts to understand a complex system by breaking it
down into its component parts. It's limited b/c parts may act different when isolated from the largest
system
What does models mean - correct answer provides a way of organizing or thinking about a problem;
may also suggest experimental approaches
What does theory mean - correct answer proposed explanation for some natural phenomenon and as a
body of concepts that explains facts in an area of study
What does basic research mean - correct answer extends the boundaries of what we know.
What does applied research mean - correct answer seeks to use scientific findings in practical areas such
as agriculture, medicine, and industry
What does phylogenetic tree mean - correct answer branching diagram or "tree" showing the inferred
evolutionary relationships among various biological species or other entities
Kingdom Plantae - correct answer organisms that have cell walls of cellulose and obtain energy by
photosynthesis
Kingdom Fungi - correct answer have cell walls of chitin and obtain energy by secreting digestive
enzymes and then absorbing the products they release from the external environment
Kingdom Animalia - correct answer contains organisms that lack cell walls and obtain energy by first
ingesting other organisms and then digesting them internally
Kingdom Protista - correct answer consists of all the unicellular eukaryotes except yeasts as well as the
multicellular algae
, atoms - correct answer the fundamental elements of matter
cells - correct answer basic unit of life and is the foundation for understanding growth and reproduction
in all organisms
tissue - correct answer groups of similar cells that act as a fundamental unit
organ - correct answer body structures composed of several different tissues that act as a structural and
functional unit
population - correct answer a group of organisms of the same species living in the same place
homologous - correct answer same evolutionary origin, but they now differ in structure and function
analogous - correct answer similar function but different evolutionary origins
cell theory - correct answer describes the organization of living systems
DNA - correct answer a long cable like molecule
gene - correct answer discrete unit of info
chapter 2 - correct answer The nature of molecules and the properties of water
What does element mean - correct answer composed of atoms that have the same atomic number
What does atomic number mean - correct answer the number of protons in the nucleus
atomic structure includes - correct answer a central nucleus and orbiting electrons
